Saving in width knitted fabric dyeing and finishing technologies
As we all know, most of knitted fabrics dyed in the dye vat to dip process, is a widely used traditional processing technology. In the textile dyeing wastewater industry faces due to a rapid rise, threatening the sustainable development of the industry today, dyeing and finishing industry is facing from the product quality, production cost and energy saving, and many other pressures and challenges. Faced with these issues, looking to a more competitive processing methods, it becomes overwhelming majority of dyeing textile machinery manufacturers and related suppliers to think and a topic of concern. >> Textile energy saving in action
Benninger company as a professional textile equipment manufacturers, has been committed to continuous fabric bleaching, mercerization, dyeing and other areas of research. Today, Benninger production of knitted fabric width dyeing and finishing equipment, including cold bleaching / scouring and bleaching, mercerization, cold pad-batch dyeing, dyeing / Printing After washing, as well as fiber cloth to wash oil, etc., are the many domestic and foreign users. In 2007, the company's knitwear width dyeing and finishing by the Chinese printing industry associations included in the first group of Chinese printing and dyeing industry of advanced technology energy saving recommended directory.
As technology advances, such as processing of fabric knitted as width processing has become a practical approach to challenges, which not only effectively solve the rope is difficult to avoid the abrasion process, cylinder poor quality, water, steam and chemicals consumption is also significantly reduced.
Cold pad-batch dyeing of reactive (CPB) as an example. CPB dyeing is a more mature way, the process is divided into three parts: the immersion water washing reaction. In the impregnation process, the temperature and the dye circulation rate, uniform linear pressure roller, fabric absorbency rate, and the fabric tension is several decisive factors. Compared with the first three points of the fabric knitted no new difficulties, "the fabric tension" that one must pay attention to. Differences in fabric tension can lead to deviations up to 30% staining.
Benninger CPB dyeing machine to hit from the cloth to set the accurate and constant volume of fabric conveyor line (Figure). If the volume into the fabric using fabric, paper on the back with a central device, then there is a sub-adjusting cloth guide rollers so that squeezed from the cloth to extract the entire treatment process and always maintain constant tension. Colored fabric padding controlled manner after the transfer guide roller through the tension of playing low volume. When the cloth roll diameter increases, the clot can move along the platform frame is air movement, thereby ensuring the stability of rolls of various conditions. Volume hours after rotating pile fabric, you can pre-washing, soaping, washing, neutralization and washing.
CPB dyeing without salt, bath ratio is about 1:1, energy saving; no scratches, clean cloth; Benninger CPB dyeing machine on the proportion of feeding, temperature and line pressure is also precise control of process conditions ensure the reproducibility of product quality. Today, energy companies will passively for the textile wastewater treatment and reuse aspects, able to actively improve the production process, improving the overall performance of equipment, in ensuring the stability of product quality while reducing the dyeing process the dye, to help agent consumption, control of pollution from the front, no doubt from another point of view to solve the wastewater problem, as more companies have found a new way of energy saving and emission reduction.
